Abstract
The utility model relates to a belt conveyor safe operation protection draw cord switch, specifically be a draw cord switch's swing arm and wire rope's connection structure. Including swing arm, wire rope, the head of swing arm is provided with a ring groove, is provided with bolt hole, nut bolt tie -rod hole in the middle of ring groove's the bottom, be provided with on ring groove's the cell wall and be used for wire rope advances the end, goes out the notch of recess, and the bolt is encircleed to the wire rope end to compress tightly in ring groove by the nut. The utility model discloses the messenger draws cord switch's wire rope to press in a ring groove, makes the swing arm and has realized being connected of wire rope swiftly, firm, solved connection that traditional wire rope card connection structure exists not the portion firmly, easily cause wire rope slippage, messenger to draw cord switch insecure problem of working.
Description
Technical field
The utility model relates to the pull switch for belt comveyer safe operation protection, specifically a kind of swing arm of pull switch and the linkage structure of wire rope.
Background technique
At present, belt comveyer is supporting is provided with pull switch, during for running into equipment and Personal Risk in running, being realized emergency braking by pull switch, being cut off the electricity supply.The connection of its swing arm of existing pull switch and wire rope all adopts wire line shoe, and this kind of linkage structure Problems existing connects insecure, easily causes wire rope slippage, makes pull switch work unreliable.
Model utility content
The utility model is intended to the connectivity problem solving above-mentioned swing arm and wire rope, and provide a kind of and can realize connecting fast, the firmly swing arm of pull switch and the linkage structure of wire rope.
The technological scheme that the utility model solves the employing of described problem is:
The swing arm of pull switch and a linkage structure for wire rope, comprise swing arm, wire rope, and the head of described swing arm is provided with an annular recess, is provided with bolt hole, nut bolt through bolt hole in the middle of the bottom of annular recess; The cell wall of annular recess is provided with for the notch of described steel wire rope end head into and out of groove, steel wire rope end head around bolt, and is pressed in annular recess by nut.
Adopt the utility model of technique scheme, compared with prior art, its beneficial effect is:
The wire rope of pull switch is pressed in an annular recess, the connection of swing arm and wire rope is achieved fast, firmly, the connection solving traditional wire line shoe linkage structure existence firmly, does not easily cause wire rope slippage, makes the insecure problem of pull switch work in portion.
As preferably, the nut portion of the corresponding nut bolt of head of described swing arm is provided with the embedded groove that embeds this nut portion.By the embedded structure in bolt nut portion, nut can be made to compress wire rope more firm, and make to keep level and smooth outside the head of swing arm, be conducive to swing arm and swing in protective housing.
